SANDING-MACHINE FOR MOLD S.

PECIFICATION forming part of Letters Patent No. 743,967, dated November 10, 1903.

' Application filed June 15,1903. Serial No. 161,551. (No model.)

To al whom, it may concern:

Be it known that I, FREDERICK J. WILns, a citizen of the United States, and a resident of Stonypoint, in the county of-Rockiand and State of New York, have invented a new and Improved Sanding-Machine for Molds, of which the following is a full, clear, and exact description.

This inven tion relates to sanding-machines for molds for brick and the like; and it consists, substantially, in 'the' construction, organization, and combinations of parts hereinafter particularly described and claimed.

One of the principal objects of my invention is to provide means for overcoming numerous disadvantages and inconveniences found to exist with many machines hitherto devisedfor similar purposes and :to provide a machine of this kind which is effective and reliable in use, "besides comprising few parts and being comparatively inexpensive to manufacture.

A further object of the invention is to provide a machine of the'character referred to which is simple in its construction and or: gauization, as Well as easily controlled and regulated, and which also possesses the capacity for long and repeated service.

The above and additional. objects are attained by means substantially such as are illustrated in the accompanyingdrawings,in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a transverse sectional view substantially on the line 1-1 of Fig. 2, showing a sanding-machine for molds embodying my improvements. Fig. :2 is a longitudinal sectional elevation taken substantially in the plane of the line 2 2 of Fig. 1. Fig. 3 isatop plan view, and Fig. 4t isan end elevation.

Before proceeding with a more detailed description it may be stated that in the form of my improvements herein shown I preferably employ means for continuously supporting a series of brick or other molds about a horizontal axis in such manner asto constitute a receptacle for the sand employed for the molds, said molds being fed to the machine intermittently and preferably one at a time, while each mold is preferably constructed for the format-ion of a plurality of bricks, as will hereinafter appear.

tinned.

I also employ suitabledistance substantially equal in extent to the width of one of the molds, thus enabling another mold to be fed to the machine, while immediately succeeding this action other suit- .able means are operated to dislodge and partiallyli ft out the uppermost mold of the series, thus permitting of the next succeeding movement of such series and the introduction or delivery to the machine of still another mold,

and soon is the operation of the machine con- I employ still'further devices or means forrpreventing the molds in the machine t'rom backing or riding up in reverse direction, and While I have herein represented my improvements in a certain preferred embodiment it will be understood, of course, that [am not limited to the precise details thereof in practice, since immaterial changes thereof my invention.

Specific reference being had to the accommachine, the same being provided at 2 2 with bearings for a longitudinal shaft 3, which is provided at one end with an arm 4, to which in may be resorted to coming within the scope is connected a crank or wrist pin 5, whereby said shaftmay have an intermittent rocking motion imparted thereto from any suitable driving power, as is apparent. Said shaft passes loosely through the central hubs 6 of substantially duplicate disks or plates 7, constituting the heads of the machine, said disks being relatively stationary and provided on the inner surfaces thereof with continuous circular tracks or Ways 8, located. a suitable distance within the edges of the disks, the said tracks or ways being formed at their inner edges with annular flanges 9, behind which the slightly-projecting portions 9 of the ends of the molds 10 are received,as shown. The disks or plates 7 are disposed a distance apart preferably slightly in excess of the length of each of the molds 10, it being noted that the latter are each constructed of a pluof striker-arms 14,normally standing radially to said shaft, (see Figs. 1 and 2,) said arms partaking of the rocking movements of the shaft and reciprocating in planes within and a suitable distance from the inner surfaces of the said disks or plates 7. The upper ends of said striker-arms 14 are connected to the .ends of a rod 15, extending between the disks 7 substantially parallel with the shaft 3, said rod having also attached to the ends thereof suitable carriers 16, each provided with wheels 17, which move or travel back and forth over parts of the surface of the adjacent track or way 8,accordingly as the strikerarms are operated in one direction or the other, as presently explained, it being noted that the said carriers 16 are connected by means of a striker 18, the function of which will be understood later on. Surrounding the said shaft 3 at places intermediate of each of the bearings 2 2 and hubs 6 are the hubs 19 of duplicate outer disks 20, the sides of the bores or openings of said latter hubs being conical or tapered inwardly, as shown at 20, so as to enable these disks to be continuously inclined inwardly at the lower parts thereof, (see Figs. 2 and 3,) in which position they are constantly maintained in virtue of the outer annular rails 21 thereon being guided between the sides of grooves formed circumferentially of rotatable pulleys or wheels 22, which are suitably mounted on portions of the framework at the lower part of the machine, as shown. The said outer disks 20 are provided with inwardly-projecting flanges 23 at the edges thereof, which serve to support the lowermost molds as the latter are continuously fed to the machine in the manner to be described, it being mentioned that these outer disks are movable independently, but always in the same direction, being thus 0perated by the weight of the lowermost molds in the machine, as will appear.

Mounted at one side of the machine on supports 24 is an inclined feed shelf or table 25 for the molds 10, said supports being slotted at 26 and having fastening-screws 27 entering parts of the framework through said slots, thus providing for adjustment, said shelf or table being preferably so connected to the supports as to be capable of slight vertical movement at its inner or lower end, thus facilitating the sliding of said molds to the machine one at a time by gravity. Working in bearings 28 therefor secured to the.

under side of said feed-shelf 25 are the ends or journals of a rocking roller 29, extending parallelwith the shaft 3 and being of a length slightly less than the distance between the inner surfaces of the disks 7, said roller having duplicate curved arms 30 pendent therefrom near its ends, said arms in turn supporting at their lower ends another roller 31 of substantially equal length, this latter roller normally taking into a crevice 32, (see Fig. 1,) formed by the abutting edges of two adjacent molds, thus preventing the molds in the machine from riding up due to any cause. Thevfeed-shelf 25 is preferably provided with side portions 33 for maintaining the molds in position thereon, and hinged or pivoted at 34 to opposite points of the top piece 35 of a frame 36, secured to said side portions at 37, are preferably duplicate curved arms 38, the free portions of which extend over and rest slidably on the upper edge of the hereinbefore-mentioned striker 18, said arms being for the purpose of dislodging and partly lifting from the tracks or ways 8 that one of the molds which is uppermost in the machine at the time all the molds in the machine are operated tobe moved forwardly, as presently explained.

In operation molds are first placed in the machine to a number sufficient to form a receptacle for the sand 39 employed for sanding the molds, it being noted that the adjacent edges of the molds fit together closely, thus preventing escape of any of the sand. The molds gravitate down the inclined feedshelf 25, and as the foremost one of the lot is delivered to the tracks or ways 8, substantially as indicated in Fig. 1, the striker-arms let are immediately operated and carried downward to the right (see dotted lines, Fig. 1) in such manner as to cause the striker 18 to impart a blow to the upper side of said foremost mold, the force of such blow being communicated to all the remaining molds in the machine and causing these molds to be moved forwardly and around upon said tracks or ways 8 a distance substantially equaling the transverse dimension of one of the molds, thereby furnishing room for the next foremost mold of the lot on the feedshelf to be fed to the machine in the same way, whereupon the operation is repeated as before, and so on indefinitely. As said strikerarms are thus caused to be carried downwardly (due to the motion of the shaft 3 in one direction) the movable curved arms 38 are likewise caused to be lowered to the position thereof indicated in dotted lines, Fig. 1, and the wheels of the carriers 16 move upon parts of the surfaces of the tracks or ways in an obvious manner. On reverse mo- IIO tion of the shaft 3, however, the striker-arms are caused to be raised again substantially to the first or original position thereof, and likewise the carriers and striker are caused to be returned therewith, and in virtue of this return movement of said striker the pivoted curved arms 38 are again elevated or moved upwardly with force, the free portions thereof coming beneath the uppermost mold in the machine at this time, thus dislodging and partially elevating this particular mold, as shown in Fig. 1, whereupon the removal of said mold may be completed by the operator and the mold placed upon a receiving-table or other structure 40, which may be erected alongside the machine for that purpose. As

-mol'ds thereof causes the outerdisks to descent'of .the striker-arms 14.- the mold that is directly struck thereby effects passing frictional engagement with the rocking roller 29, causing the latter to rock-or turn in such manner as to carry the pendent curved arms 30 thereof outwardly (see dotted lines, Fig. 1) and which action of course releases the roller 31 from any engagement it may have with adjacent molds, thus facilitating operations, as is apparent. The arms 30 and roller 31 are im mediately restored by gravity to their former positions, however, the latter serving to prevent movement of the molds in the machine except in the direction intended therefor. Of course as the molds in the machine are successively and intermittently passed through the machine in the manner described quantities of sand are taken up thereby and subsequently emptied therefrom as the molds are inverted orturned upside down, which is practically the final position assumed by each mold. It may be stated that the machine is never completely filled-with the molds, since provision is necessary for the described movements of the striker-arms and the parts directly coacting therewith, as will be readily understood.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
